Fragrance Engine vs SillagePro

Excel is great when you already know what to type into the cells. A formula generator is what you reach for when you want the math to check itself and the regulator to never come knocking.

Perfumer's Companion is a calculator. Fragrance Engine is the calculator plus the engine that decides what to mix in the first place.

Note libraries answer 'what is this material'. A formula generator answers 'what should I do with it'.

Formulair is well loved for good reason: if you compose at the bench on Apple devices and want a clean, offline, buy-it-once place to store, scale, and dilution-track your work, it is excellent. Reach for Fragrance Engine when you want the software to draft a formula from a written brief, read its structure back, price it from live suppliers, and share editions with a community, on any device.

PerfumeLab is a capable Apple app: it builds and scales percentage formulas, reads their structure, monitors limits, and exports a clean PDF. The difference is the front and back of the workflow. Fragrance Engine starts the formula from a written brief and ends it with live supplier prices, a cost optimizer, reformulation, and a community library, in any browser.

The Perfumer's Workbook is a serious, long-established desktop program, and its professional material database is far deeper than ours. If you want an offline archive with thousands of materials on a one-time or institutional licence, it is a real option. Fragrance Engine trades database depth for a browser-based workflow that drafts from a plain-language brief, prices from live suppliers, and starts at $12 a month.

Perfumer's Vault (the M24 Media app, not the unrelated open-source ParfumVault) is a capable cross-platform vault with inventory, supplier tracking, and an AI generator wired to Google Gemini. The core difference is reproducibility: its output is a language model's, so the same brief can give a different blend each time. Fragrance Engine's generation is deterministic, the same brief returns the same formula from a curated catalog, and it adds a community library and live supplier pricing.

SillagePro is a genuinely useful free tool: a clean manual builder with a large material list, cost and concentration tracking, inventory, and a step-by-step making mode. If a manual builder is all you need, it is a fair pick at no cost. Fragrance Engine is for when you want the software to draft the formula from a brief, read its structure back, and reformulate around a material you cannot get, with a community library to publish into.
